Mastic sealing for commercial buildings in Laverstoke
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Laverstoke carry our 12-month guarantee. Site teams most often ask us about damp patches beside frames and mastic failing across several blocks on an estate, across communal kitchens and washrooms, communal entrances and stairwells and window and door perimeters on blocks. A specialist sealant contractor works differently from a general builder: on jobs in Laverstoke, preparation and product choice get the time they need.

Blocks and managed buildings in Laverstoke
Laverstoke is about 55 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Laverstoke is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
For agents with blocks near Whitchurch (Hampshire) station, 1.7 miles west of Laverstoke, a block-wide mastic programme deals with frames, balconies and entrances in one go. If your remit includes a building such as Testbourne Community School, frame and door mastic can be programmed for the holidays.
Laverstoke is about 8 miles east of Andover, in Hampshire.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Laverstoke may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
- Water coming in from the roof or rainwater goods
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
What we’re called out for in Laverstoke
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
If one of these sounds familiar, it’s time for a closer look:
- Estate-wide sealant that is simply worn out
- Draughts at frames across a block
- Brittle perimeter mastic across a building
- Water getting in round frames after rain
Trustees of buildings like St Nicholas' Church can bring frame and external mastic into a planned maintenance list.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
Questions we’re asked in Laverstoke
Is Laverstoke too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you work for managing agents with blocks near Whitchurch (Hampshire) station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work with property factors and landlords?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Work for main contractors and building owners
Building owners and managing agents use us on everything from one building to a spread of sites around Laverstoke. Several sites can go on one quote, which keeps the paperwork simple.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
